volvo 86

HI every one I have a 1986 volvo 240D just tune-up changed air filter -spark plugs wires -spark plugs - fluel filter- rotor -rotor cap-
almost everyting but when I start the car just stays running for like 10min then dies so my question IS THIS WHATS WRONG WITH THE CAR HAS LIKE 160.000MILES CAN BE THE FUEL PUMP ? LOW COMPRESSION , OR JUST OLD CAR

1991 Nissan MaximaSE; V-6, 3.0 liter w/ 175K miles.
The owners manual states that the timing belt must be replaced every 90K miles. I had it replaced at 92K. Now that the car is approaching the 180K mark, do I need to spend the $$ on doing it again or should I just drive it until it breaks?
I have maintained this car over the years (new altinator, brakes,exhaust, water pump, transaxle shafts, fluid changes on everything, battery, plugs, wires and so on) and recently bought Momma a new car (2003 Mazda6s). Since the car doesnt have much value left, I decided not to trade it in. Instead, my father-in-law needs a car and this is what he's getting. The maxima runs great and I was wondering if I should replace the timing belt a second time before it goes to the in-laws... I had the dealer do the first belt, since it looked like a pretty big job
Thanks in advance,
Dean

Have a 87 Cad Deville that I would like to pull the V8 and tranny and replace with the V6 and tranny. Has anyone got any experience with this swith? The car is in great shape but the engine and tranny are tired.:)
